Make glass lightbulb material work?
I would think you could use a principled shader with the transmission level set to 1.  Here's a demo scene:

There's a cylinder inside the first sphere and it acts as the filament:

The plane and the back sphere have simple principled shaders.  The only changed setting on either is the color.
The front sphere has a principled shader with roughness well down and transmission set to 1:


Note: if you look at this scene in Lookdev/Viewport shading you won't see the filament because EEVEE is used in lookdev:

My world emits no light and there are no other lights in the scene but the filament:

and the filament is just an emitter:

The blackbody simply sets the color to daylight.
Here's the render view with that setup:

or you can set the color to reddish by changing the temperature to 1500:

or lower the intensity of the bulb:

note that the yellow outline of the cylinder is because it's selected.  Here's an actual render:
